A Halloween display at 352 W. Longden Ave. in Arcadia has a “Davy Jones” theme and features a pirate ship spanning more than 20 feet in length and a maze. Every year, crowds flock to the block, which has become known locally for its lavish Halloween displays, resident Gloria Lau said in an e-mail. “You are lining up like you are going on a Disneyland ride,” she writes. Another home nearby has “flying ghosts, lights and many special effects,” according to Lau.
